D1U3CS-D-850-12-HxxC Series
DC/DC Front End Power Supply
PRODUCT OVERVIEW
The D1U3CS-D-850-12-HxxC series are highly efficient 850 watt, DC input front end supplies with a 12V main output
and a 5V or 3.3V (20W) standby. They have active current sharing and up to 8 supplies may be operated in parallel. The
supplies may be hot plugged, they recover from overtemperature faults, and have logic and PMBus status signals. Their
low profile 1U package and >15W/cubic inch power density make them ideal for delivering reliable, efficient power for
telecom and other 12V distributed power systems that include servers, workstations and storage systems.
FEATURES
n 850W output power
n 87% efficient at half power
n 12V main output
n 3.3V or 5V standby output of 20W
n 1U sized; dimensions 3.20”x11.00”x1.57”
n 15.4 Watts per cubic inch density
n N+1 redundancy capable,
including hot plugging (up to 8 in parallel)

ORing FET
n Overvoltage, overcurrent,
overtemperature protection
n Internal cooling fan (variable speed)
n PMbus / I²C interface with status
indicators
n RoHS compliant
